Abstract

THE INVENTION RELATES TO A CLOSED CONTAINER. THE SET CONTAINS A BODY 1 AND A COVER 2 MUTUALLY SEALED AT THE ORIGIN. THE BODY HAS A MOUTH WITH STRIP 10 ATTACHED TO THE COVER AND IS PROVIDED WITH A WEAKNESS ZONE 6 OR SLOT 7 IN THE VICINITY OF THE STRIP WHERE THE CONTAINER MOUTH IS ATTACHED TO THE COVER. THE WEAKNESS ZONE CAN BE BROKEN TO OPEN THE CONTAINER. PART 25 IS TO REASSEMBLE THE COVER ON THE CONTAINER. IN THIS WAY A CONTAINER WITH A REMOVABLE LID IS OBTAINED, WHICH CAN BE REPLACED IN A WATERTIGHT MANNER.

Description

The present invention relates to a container which is in a state

waterproof at the origin and

  likely to be opened and then closed again.

  container comprises a container body and a cover

  The container body is constituted by a container wall with an edge portion comprising a flange extending outwardly from

  of the container wall, which is provided with a

  size or area of weakening and part of

  peripheral detention outside the zone of

  The cover includes a central portion or section, a peripheral retaining portion or section sealingly attached to the collar retaining portion and an intermediate section or portion defining an enclosed space which is

  downward and which includes a superior wall

  an inner side wall and a side wall

  and which is arranged to interact on the portion or section forming the edge of the container body when the container is closed after its initial opening. U.S. Patent No. 2,998,158 discloses a container of the aforementioned type where the zone

  of weakening is arranged in two

  of the lid and the elements forming the collar of the container body, the container being

  opened by tearing off an external strip that is

  killed radially outside the weakened area

  and that Hermeticity should be discarded

  closing is only obtained by a contact

  surface area between the curved middle section of the

  circle and the part of the edge shaped cor-

  respondent and their flange elements

  of the original closure and the reclosure, the

  vercle takes the same position relative to the body of the container, which means that the lid, both before the opening of the container after its reclosing, abuts rigidly against the container body In addition, it is difficult to grip the lid after it has been closed, due to the location and construction of the weakening zone, so that the outer edge of the lid and the outer edge of the edge or bead portion are located adjacent to one another; on the other and together form a substantially equal surface Another disadvantage of the construction disclosed in US Patent No. 2,998,158 is that the weakening notches in the lid and in the elements which form the collar of the container body must be aligned with great precision relative to each other to make the grubbing

  or the tearing of the zone of weakening possible.

  This requires high precision during the manufacturing process.

  cation of both the lid and the container.

  British Patent No. 1,473,905 describes a construction according to which the opening of the

  container is facilitated by a selvedge on the cover

  cle, which extends from the section forming edge or bead of the container This is obtained by placing the zone of weakening in the vicinity of the part

  forming an edge or bead of the body of the container in the

  This groove has the disadvantage that there is no possibility of sealing between

  the lid and the elements that make up the glue

  rette of the container by a permanent connection, as

  by welding, gluing and the like.

  container has all of the above-mentioned disadvantages with respect to the container according to the US patent

of America No. 2,998,158.

  The present invention therefore more particularly

  purpose of which is a container which eliminates the incon-

  mentioned above and which is originally welded to a

  in an airtight manner and which, at the opening of the

  originally welded container, leaves no

  part to be discarded and that can be closed with

  leakage on the lid on the body of the

  container, a gripping device being available

  ble to facilitate the opening of the closed container.

  The present invention also relates to a container according to which the opening of the container

  welded to the origin is facilitated by

  vier. When opening the container according to the present invention, a reinforcement of a peripheral collar of the lid is obtained by attaching a portion of the collar of the container which remains

  subject to rupture of the weakening zone.

  This allows a saving of material, since at least the part of the lid to which the collar of the container is secured may be relatively thin. According to one embodiment of the invention, an elevation is provided on the edge portion

  or bead substantially close to the area of

  in order to engage or adapt to a part forming a snap-in element

  cover to obtain the above-mentioned lever action

  when opening the container.

  In order to guarantee a hermetic closure of the

  originally sealed container, the collar of the container body is fixed and permanently sealed to the peripheral collar of the lid, for example by welding Between a central portion of the lid and the peripheral collar of the lid, there is an intermediate portion which in the originally sealed container takes a higher position in accordance with

  to which the upper wall of the intermediate part

  diary is spaced above the collar of the container body The intermediate portion forms a space

  enclosed with the collar of the body of the container

  size or area of weakness defines a locking portion that remains attached to the container body

  on breaking the notch, said notch being sensitively

  aligned with an outer side wall of

  the intermediate section The body part of the

  outside the notch and the peripheral collar of the cover which is attached to it form

  holding or holding parts which are mutual

  permanently united, so as to constitute

  a gripping element for opening the container.

  After the sealed container was originally

  green, the part of the collar of the container body outside the notch forms a unit with the lid The intermediate portion of the lid and the locking portion of the container body are provided with means for sealing the

  lid on the body of the container when

  setting of the container, the cover then taking a lower position according to which the locking portion is received in the space in the part

  Another feature of the invention lies in the fact that during the breaking of the notch, a locating surface is formed on one of the broken parts of the container at the notch and that this locating surface cooperates with a commitment device. or contact when the lid is placed on the body of the container to give an action to

sudden engagement.

  In accordance with a particular embodiment

  of the invention, a locking part

  re attached to the container body after breaking the notch and said locking portion is inserted or inserted into a hollow space in the lid

  to perform the snap action.

  According to yet another embodiment, the wall of the container body undergoes a commitment or

  contact with the lid to give a second

  gion of engagement or contact when the lid is

  re-engaged on the container The second region of re-

  Referring now more particularly to Figure 2, there is shown a portion of a hermetically sealed container, consisting of a container body 1 and a lid 2, each made of a plastic material. The container body comprises a wall

  of container 3 with a mouth comprising a glue

  5 extending radially outwardly

  shot from the container wall around the entire mouth

  and which came from the material with the wall of the

  in one part constituting the edge or bead 4,

  The container may have a shape

  appropriate, as a circular, rectangular shape

  gular with rounded corners, or oval.

  As FIGS. 1 and 2 show, the flange 5 of the container body is flat and

  extends perpendicular to the axis of the body of the

  The flange can also be directed downwards or upwards to form an angle with the axis, which goes up to 900. The flange is provided with a circumferential weakening zone 6 which, in

  the embodiments shown in the figures

  1 and 2, is formed by a groove, groove or

  size 7 in the lower surface of the flange and which is disposed at a predetermined distance from the axis of the container body or the inner surface 8

  of the container wall 3 In the form of

  1 and 2, the groove or groove 7 is formed in the lower surface of the

  flange, but the weakening zone may also

  be obtained by arranging a groove similar to the upper surface or by making grooves or

  grooves in each of the surfaces-of the collar.

  When the collar is broken at the notch 7, the flange is divided into two functional pieces consisting of an inner locking portion 9 and an outer holding or holding portion 10 The inner locking portion 9 will be formed with a

  surface location or external housing on rup-

  the notch, to cooperate with the lid to establish a sealed state, the lid on the container body when the container is closed, as will be explained in more detail in

following this memoir.

  The lid 2 comprises three functional parts

  in the form of a central closing and sealing part 11, a retaining or holding part

  12 and an intermediate locking portion

  Continuous circumferential contact surfaces During

  of the union process, energy is provided to the -

  contact surface, for example in the form of heat, ultrasound, high frequency oscillation or

combinations of these means.

  In the embodiment shown in FIGS. 1 and 2, the retaining or holding portion 10 has a planar top surface, while the retaining or holding portion 12 is provided with a circumferential weld marking 15 on its face. lower, which allows the use of an ultrasonic weld

  a break in the weakening zone 6 and possibly

  also by the fact that the lid adopts totally or partially a position closer to the body of the container than is the case of a container

with an undisturbed closure.

  The central part 11 of the cover comprises a vertical wall 16 which, in the initial sealed closure, as shown in FIG. 2, forms a tolerance space 17 with the inner surface 8 of the wall 3. In this way, a weld is avoided. undesired of the wall 16 to the wall 3 when

  the holding or retention part 10 is joined to the

  The method of joining the retaining or holding portion 10 to the retaining or holding portion 12 is then adapted to the contact existing between the wall 16 and the wall 3. The wall 16 is substantially juxtaposed with the upper part of the wall of the wall. container and is substantially vertical in the embodiment

  shown in Figure 1 In addition, in order to ensure

  to each other during the closing operation.

  The intermediate locking portion 13 is U-shaped and protrudes over the edge or bead 4 so that the upper wall 20 of the intermediate portion 13 is located in spaced relationship with the flange 5 in the initially unstable state. open and sealed container The lid adopts

  thus an initial upper position A side wall

  intermediate-13 includes, in addition, a side wall

  external wall 22 which is opposed to and spaced apart from the inner side wall 21 The outer sidewall 22 extends downwardly from the top wall 20 and merges with the retaining part or peripheral support The walls 20, 21, 22 of the intermediate portion 13 define a U-shaped circumferential space or groove 23, of a predetermined size which is adapted to receive the bead or edge 4 of the container body to close this container. after its original sealed seal has been broken The edge portion or bead 4 therefore effectively forms a locking member which penetrates into the gap 23 when the container is closed. The outer side wall 22 has an inner surface 24 which

  is aligned with the weakening zone 6, that is,

  say the notch 7 of the flange-shaped element and is provided with a bulge in the form of a

  inwardly directed heel 25, which extends from

  circumferentially to form a portion of a snap-in element for

reclosing the container.

  During the opening of the originally sealed container, the retaining or holding member 10 and the retaining or retaining portion 12 therein are moved substantially axially and, more particularly, upwardly, that the flange breaks at the weakening zone formed by the cut 7

  container is closed by pressing the glass part

  rusting 13 of the lid on the edge or bead 4

  so that this edge or bead penetrates into the

  ge 9 of the collar, formed by the rupture of the

  size, constitutes the second part of the element of

  abrupt engagement and the locating or housing surface engages abruptly behind the heel 25, against the inner surface 24, together with the opposite inner surface 8 of the wall 3

  inner king 21 At least the upper part of the

  inner surface 8 of the wall 3 is shaped by

  port to the inner surface 26 of the side wall

  dull 21 to ensure good surface contact A

  such a surface contact is obtained in the form of

  shown in Figure 2, by the fact that

  the surface 26 of the inner side wall 21 is

  slightly radially outward in relation to

  at the lower outer surface of the wall 16.

  If the container is intended for cheese and

  logues, which is cut with a wire or

  similarly during filling, the edge 4 should be shaped with a heel or the like which extends upwards and serves as a guide or support for the wire, so that the wire cleans the welding surfaces of the wire. container on the upper surface of the collar, which are located in a plane lower than the plane of the heel surface.

  According to another embodiment,

  a second snap-in element that pre-

  in the form of a heel and a groove is arranged on the cooperating surfaces 8, 26 when it is necessary to powerfully hold the lid

  on the closed container In the majority of applications

  In this way, a satisfactory and sufficient sealing and locking is obtained with the first sudden engagement element described.

  It is also possible to omit the first element of

  abrupt clipping and to foresee only the

  snapping on surfaces 8, 26.

  Apart from the advantages mentioned, the described embodiment also offers the important advantage that, in the original closure, the locking and central parts 13 and 11 are axially

  mobile, that is, elastic, because of the pre-

  presence of enclosed space 23 in Part 13 and

  the internal optimum groove 18 in the central part 11.

  This elasticity is desirable from the point of view of preservation and transport, in that a container

  hermetically sealed is not as easily

  damaged by a natural or negligent manipulation, or in the case of an overpressure that would occur

in the container.

  Figures 3 and 4 show other forms of

  making a container according to the present invention.

  The same reference numerals have been used to denote the same elements in the figures, and similar but modified elements are designated with prime signs. In the embodiment shown in FIG. 3, the collar 5 'of the body of the container comprises two flat parallel parts 30, 31 which

  are located at different levels and with a

  predetermined cement with respect to each other

  connecting part 32 joins the parts 30 and 31.

  The locking portion 131 of the lid is received in a pocket or shoulder formed by the connecting portion 32 and the lower portion 31 of the collar. The retaining or retaining portion 12 of the cover is secured to the upper part 30 of the flange and is in the same plane as the upper wall 20 'of the intermediate portion 13' of the cover The function is the same as that

  described with respect to the embodiment

  shown in FIGS. 1 and 2 The embodiment

  shown in Figure 3 allows the use of a

  flat upper sealing tape 33 which simplifies the positioning of the container body and lid

  In the embodiment shown in Fig. 3, the container body is provided with a lower guide member which also exerts a reinforcing effect and which comprises a collar 35 and a multiplicity of radially disposed walls 36 between the collar. The radial walls 36 have angled guide surfaces 37 which contact the tool or other guide means when the container is in position for union, for example in a cassette. also be

  According to a preferred embodiment of the invention,

  In this invention, the container is provided with a region or zone defined to initiate the opening of the container. This region is indicated by an attachment indication in the form of a tongue or tab 41 extending towards

  the outside from the part 10 of the collar 5.

is present.

  In the arrangement with the lever action according to

  FIGS. 5 and 6, the heel 25 of the part of ver-

  rusting 13 has a dual function, namely that it co-operates with the elevation 42 of the edge portion or bead to provide leverage on the

  weakened zone and serves as an element of

  positive abrupt engagement with the locking portion 9 of the locking portion when breaking the notch 7 The elevation can also be achieved on other containers that fall within the scope of the invention, for example, in relation to the containers shown in Figures 3 and 4 o the heel 25 is aligned on or immediately inside

the weakening zone 6.

  Figures 7 and 8 show embodiments according to which the surface which confines inside the enclosed space 23 is defined by the surfaces 46 of a multiplicity of hanging ribs

  which are also spaced around the lid 2.

  The surfaces 46 of the ribs 45 cooperate with the sur-

  inner face 8 of the wall 3 when the locking portion 9 is engaged in the groove or space

  In FIG. 7, it can be seen that the inner surface 8 of the wall 3 is provided with a step Ba such that the surfaces 46 of the ribs 45 are in spaced relation with the wall in the position initially

  when the notch has been broken and the recess

  then closed, the abrupt engagement of the heel 25 with the locking portion 9 is concurrent with the engagement of the surfaces 46 of the

  ribs 45 with surface 8 beyond step 8 a.

  In this way, a tight and airtight fit between the surfaces 46 and the inner surface 8 of the container wall 3 in the closed state can be achieved. The embodiment illustrated in FIG.

  As previously noted, the container and

  the accompanying lid may have multiple

  cross-sections Figure 9 and 10 show

  an embodiment of rectangular outline whose cross-section is the same as that

  shown in Figure 2 However, we could also

  use the cross-sections of other

  embodiments in the embodiment

  The cover is then folded upwards, as shown in FIG.

  10, to allow emptying the contents of the container.

  In order to close the container, the lid is folded down and a snap is made between

  More particularly, in FIG. 11, the container body 1 comprises a container wall 3 as previously described, but instead of the simple flange made of material, 5, as in the case of the previous embodiments, the body of the container body 1 comprises container 1 utilizes an outwardly facing material edge 49 to which a separate element 50 of cross-section L is secured. The edge 49 and

  element 50 form, in a cooperative manner, a

  Likewise, the surface 8 'of the locking portion comes into contact with the surface

26 of the wall 21 of the lid.

  The construction as represented on the

  gure 11 is somewhat simplified compared with the

  the above-mentioned embodiments, since the lid can be formed without the need to make the heel 25, and the container body can be formed without the need for a reinforced edge or bead portion 4 The lid 2 and the container body can each be shaped with a uniform thickness everywhere. The separate element is of simple configuration and can be easily formed and secured to the edge 49 and then attached to the lid after the contents have been introduced into

the recipient.

  It is evident from the description

  which precedes that the invention relates to the combination of a container and a lid, according to which the lid is initially sealed to the container and can be removed from the container to open the container.

  and then be placed back on the container to close it.

  The assembled combination is meant to indicate to the user

  sator of tampering or tampering, since the state of the initial seal is evidenced by the continuity of the cut. The container comprises a body 1 having a mouth which comprises

  a strip 10 of annular nature attached to the cover

  One of the elements formed by the container and the

  cover is provided with a zone of weakening

  as well as the strip separate from the body to provide

  two separate parts that can be brought into contact by replacing the cover with the

  separate strip attached to the container.

  The zone is located radially inside the strip and by breaking of this zone is formed a

  location or housing surface for replacement
